bnx2: fixing a timout error due not refreshing TX timers correctly
When running the following script on an active bnx2 interface:
while(true); do ifconfig ethX mtu 9000; ifconfig ethX mtu 1500; done
A timeout error appears and dumps the following stack:
NETDEV WATCHDOG: eth4 (bnx2): transmit queue 0 timed out
------------[ cut here ]------------
Badness at net/sched/sch_generic.c:261
<snip>
This patch just fixes the way that ->trans_start is refreshed.
